摘　　要：动态可重构技术在降低机载嵌入式计算机的体积、重量和功耗方面有巨大的潜力。分析机载应用环境对嵌入式计算机的要求,探讨部分可重构和软件可编程重构两种动态可重构方法,并针对机载嵌入式计算机的需求,从硬件资源利用率、系统灵活性和系统可维护性等方面详细分析比较了两种动态可重构方法。基于部分可重构方法,提出了一种高性能、高灵活的体系结构,有效提高了系统资源利用率,具有深远的军事应用前景。Dynamic reconfiguration has an enormous potential to reduce size,weight and power consumption of airborne embedded computers.Firstly,the requirements of airborne embedded computers are taken into consideration.Secondly,two approaches of dynamic reconfiguration are introduced and studied,including partial reconfiguration and software programmable reconfiguration.Thirdly,in order to adapting the airborne embedded environment,we analyze and compare these two methods of dynamic reconfiguration in respects of hardware utilization,system flexibility and system maintainability.Finally,based on the partial reconfiguration,a high-performance and highly flexible architecture is presented,which improves the utilization of system resources and has a far-reaching prospect in military applications.
